Impulse Radar Analysis.

Abstract

Impulse radars are of interest because of their range resolution. As such they have been widely used in radar and remote sensing for target signature analysis and identification/classification. A comparison of an pulse waveform and a pulsed continuous waveform (CW) is analyzed. For each waveform, a Finite Difference Domain (FDTD) algorithm is used to obtain the radar cross section for three perfect conducting objects. It is shown that by having a larger frequency bandwidth, the impulse waveform is able to excite target resonances that cannot be excited by the pulsed CW waveform. Therefore, the impulse waveform provides greater resolution of an object.
